The establishment of the jurisdictional limits of the riparian States has become one of the major challenges of the international law of the sea. The delimitation of the maritime areas holds a privileged place in international jurisprudence. The number of delimitation treaties is also considerable. The seminar will offer to discuss the most important issues in this area as well as the relevant case law. Particular attention will be paid to the role of equidistance, equitable principles and equitable result, the determination of the relevant circumstances for maritime delimitation, the impact of islands and other maritime features, the existence of regional rules, the establishment of a single maritime boundary for different areas and other issues currently under discussion. The final questioning will focus on the possibility of reaching a general method of delimitation of maritime areas in the light of recent case law. A moot court on a contemporary delimitation dispute will be organised for the participants.
